DataCenter


Overview

So you’re working with SLES or SLED, and someone asks you if a particular package or product is supported. What do you do? Of all the options available, I refer constantly to the following pages and references to make sure I give accurate and helpful information to the querying person.

Where to Go

The top page I usually refer people to in this case is the Tech Specs section. On this page is listed SLES, SLED and Partner hardware and software support links. If I click on the “SuSE Linux Enterprise Server” link, I will reach the technical specifications page for SuSE Linux Enterprise Server. We’ve seen this page in other posts, such as How Many ____’s Does SLES Support? – Part I, where we discussed Kernel Limits and File System Features.

The chief thing I want to determine when someone asks me about a particular package’s support is that we do include it in our distributions. I query the person about what version and patch level they want to know about, and then click on the appropriate link, which is listed in the paragraph below the menu tabs, “see the list of supported packages”.

This link leads me to the “SuSE Linux Enterprise Server Supported Packages page, where for example I will pick the link for “SuSE Linux Enterprise Server 10 SP1 for X86“, a PDF file that I can then search for a package by pressing Ctrl-f, and typing the name I’m looking for, either in my browser, or my PDF reader that popped up.

All Together Now

My example would be someone asking me if there is support for Mono (a Dot Net compatible server solution) on SLES 10 SP1, both on the X86 and System Z platforms.

Those PDF files will tell me very quickly that there is support all the way to Level 3 for SLES 10 SP1 on X86 and the IBM System Z Mainframe.

Hopefully this will help you determine quickly what packages are included in the various distributions and patch levels, and make it easier to find what level of support is provided for those packages.

Enjoy,

Return on Investment… the holy grail of IT.

Simply put, ROI is defined as the “ratio of money gained or lost on an investment relative to the amount of money invested”. One formula used to determine ROI is “net income plus interest divided by the book value of assets equals Return On Investment.“

In real terms, when you invest in a technology for your business, it’s about more than that. IT-related ROI often needs to provide cost savings, rather than generate revenue. In the case of virtualization for consolidation, this is often a simple calculation made difficult by many variables.

On top of all these customers, several other developments in the relationship have occurred during the first year. Novell and Microsoft have completed building out and are now doing real engineering work and interoperability testing in the Microsoft and Novell Interoperability Lab in Cambridge, Massachusetts. More info on the lab is in the recent press release. Dell signed on as a partner for the agreement as well, working to help Linux customers with SUSE Linux Enterprise Server.

And most recently, Novell and Microsoft extended the agreement by agreeing to work together to make it easier for all software developers to develop applications for users with disabilities, such as blindness. From the press release:

Microsoft will make available its User Interface Automation (UIA) specification, an advanced accessibility framework that simplifies the development of assistive technology products for people with one or more disabilities, and pledge not to assert any Microsoft patents necessary to implement the specification against anyone, regardless of platform, in the open source and proprietary software communities. In concert, to promote interoperability between leading accessibility frameworks in the market, Novell will develop and deliver an adapter that allows the UIA framework to work well with existing Linux accessibility projects and complement the investments made by IBM Corp. and others. Novell’s work will be open source and will make the UIA framework cross-platform while enabling UIA to interoperate with the Linux Accessibility Toolkit (ATK), which ships with SUSE Linux Enterprise, Red Hat Enterprise Linux and Ubuntu Linux. The UIA solution will ensure interoperability of nonvisual access to the next generation of software applications.

“Microsoft’s commitment to make the specification for UIA freely available to others to implement, coupled with Novell’s plans to develop and deliver an adapter that allows Linux accessibility projects to work well with the UIA framework, are tremendous examples of how industry can come together to tackle interoperability problems for blind persons,” said Dr. Marc Maurer, president of the National Federation of the Blind. “The NFB challenges the entire IT industry to continue to look for creative opportunities such as this to solve longstanding interoperability challenges and reduce development barriers to accessibility.”

From the article:

The emergence of global standards for measuring the energy efficiency of datacentres moved a step closer yesterday with the launch of a raft of new research papers from green IT industry consortium The Green Grid.

The consortium has released an updated version of its Datacentre Energy Efficiency Metrics whitepaper that incorporates infrastructure efficiency into the original metrics.

It also said that it expects its Power Usage Effectiveness (PUE) and Datacentre efficiency metric for assessing the proportion of power going into a datacentre that is used to power the IT kit to be adopted by the industry and used by all datacentres to report their efficiency.

Virtual Machine Additions for Linux are designed to improve the usability and interoperability of running qualified Linux operating systems as guests or virtual machines of Virtual Server 2005 R2 SP1.

Now with support for SuSE Linux Enterprise Server 10
Microsoft is committed to testing and supporting many third-party operating systems for use as guest operating systems on Virtual Server 2005 R2 SP1 virtual machines. To help make sure that you have a favorable experience when you run third-party guest operating systems in Virtual Server 2005, Microsoft Product Support Services (PSS) has created a product support model for these third-party guest operating systems. This support model is consistent with the support model that is used for Virtual Server 2005 R2 SP1. Product support for the Virtual Machine Additions will be provided through the normal support channels available for Virtual Server 2005 R2 SP1.

CHICAGO — At the Data Center Decisions conference in Chicago on Monday, Oct. 22, controversial comments from Jon Toigo, CEO and managing principal of Dunedin, Fla.-based Toigo Partners International LLC, had attendees shaking their heads in bewilderment.

For one, Toigo advised attendees against using VMware in favor of mainframe systems, calling the virtualization software “shoddy” in comparison. But nearly all conference attendees were assembled to learn about implementing virtualization in their data center.

Toigo is knowledgeable about disaster recovery (DR) planning, which was the topic of his keynote session, but he warned users against ever feeling completely secure with their disaster recovery plans.

Ok, so my title is a little misleading, there’s not any rivalry between the different areas of Novell and SUSE, other than the usual desire to see your business unit succeed just a little more “betterly” than the other units do. It’s all about friendly competition.

What’s Red vs. Green?

What I’m referring to (with Red vs. Green) is the necessary dividing line between the traditional Novell business units like Workgroup (Netware, Open Enterprise Server, Groupwise etc.) which I think of as “Red”, and the newer and Open Source-centric business unit called Open Platform Solutions (SLES, SLED, SLERT, SLEPOS etc.), which I think of as “Green”. (Get it? SUSE Green, like the Gecko?)

I have come up with the analogy and strategy of Red vs. Green as a way of helping partners, customers and the casual passerby understand that depending on which Novell/SUSE products they have, they will likely benefit most from a particular set of products and growth options.

“I See Red”

My experience has been that if a customer is “Red”, they’re almost always firmly ensconced in and using the Novell services throughout the enterprise, with some confusion as to how and why they might make use of Linux. The first order of business is to determine how much they know about Linux in general, and in particular Novell’s use of SUSE Linux Enterprise in it’s product lines. After hundreds of these discussions, we can get everyone on the same page with a little discussion, some Q&A and a handy whiteboard in short order.

How Does This Work?

For example, in a conversation with faux customer Air America, I find they have a long-standing Netware infrastructure for File and Print, do a little clustering for Groupwise and use iPrint for printing with all account management taking place through an Identity management setup and eDirectory. They have Windows workstations that make full use of the Netware Client and it’s services. I’d already lean toward “Red” strategy with them, but they might be toying with the idea of going “over to Linux”, so I go a little further.

The questions I ask them are very simple and straightforward:

  • Do you have any data on NSS volumes?
  • Do you use any of the advanced features of NSS?
  • Do you have Novell Clustering Services or Business Continuity Clustering set up?
  • Do you have a very large number of printers?
  • Do your people have Novell Client software on their computers for access to the network?

A “yes” answer to any of these questions points to the Open Enterprise Server (with Version 2, OES = Linux base, Novell’s standard services converted to run great on Linux layered on top). Novell has spent a lot of time and effort to make it as effortless as possible to have this type of organization migrate up to OES, there is a very complete and clear path for this customer to begin to use Linux-based Novell services with the least disruption possible and often at a considerable cost-savings.

I will try if possible to help them see where “Green” might fit in, either for hosting Groupwise or other services, such as Mono (Dot Net compatible server), Virtualization (Xen) or any of a host of other possibilities. Usually this type of customer will stay “Red” and for good reason.

“It’s Easy Being Green”

On the other side of this equation, I will find customers who don’t have a lick of “Red” in their environment, and these are usually standard UNIX shops on the server side, usually either a Solaris or AIX flavor, some HP-UX, but they’ll be using mostly Windows on the client side. Usually if they say “No” to my “Got any Novell products or Netware around?”, they will go “Green” easily.

The discussion with this client is much easier, they’re a classic “Green” customer, all the services and tools they are used to using have an analog (equivalent) in the SUSE Linux Enterprise Server/Desktop product line. Once I determine they have no Netware products in the organization, we don’t even talk about “Red vs. Green”, it’s not relevant, they can even run eDirectory and Zenworks Linux Management on SLES, no “Red” needed.

I additionally will probe to see if they have any Terminal Server or Citrix/Ericom deployed for application security and updateability, if they do, it makes the Linux Desktop play much more likely, especially if they make use of TS/Citrix as a desktop solution. How compelling is $50 or less a seat for the presentation OS on the desktop versus $239 or so for the oddly-shaped box o’ Vista?

Got any changes or suggestions to this whole Red vs. Green thing? I’m constantly getting feedback and changing it, let me know and I’ll credit you and update it.

Enjoy,

Sick of hearing about “Green” yet? Better learn to deal with it, “Green”‘s drumbeat is really just beginning and it’s not just a fad, it’s something that fits a condition we have in IT, and it’s a way to get more money and headcount for managers, so listen up.

What is “Green” computing? Here’s as good a definition as I could find, click through for more from Techtarget.

Green computing is the environmentally responsible use of computers and related resources. Such practices include the implementation of energy-efficient central processing units (CPUs), servers and peripherals as well as reduced resource consumption and proper disposal of electronic waste (e-waste).

One of the earliest initiatives toward green computing in the United States was the voluntary labeling program known as Energy Star. It was conceived by the Environmental Protection Agency (EPA) in 1992 to promote energy efficiency in hardware of all kinds. The Energy Star label became a common sight, especially in notebook computers and displays. Similar programs have been adopted in Europe and Asia.

How “Green” is your office environment? Take the Greening the Cube Farm quiz and see!

Last but not least, is buying “Green” storage for business continuity, disaster recovery and archival enough? Not nearly enough, according to the marketing director of Overland Storage.

From the “About” page for VirtualBox:

innotek VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

Some of the features of VirtualBox are:

  • Modularity. VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don’t have to hack the source to write a new interface for VirtualBox.
  • Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
  • Guest Additions for Windows and Linux. VirtualBox has special software that can be installed inside Windows and Linux virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window).
  • Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, VirtualBox allows for declaring certain host directories as “shared folders”, which can then be accessed from within virtual machines.

VirtualBox is now included as a virtualization option in the openSUSE 10.3 release, available here. If you’re on another version of Linux, you can get more information about VirtualBox here, and download the binary and source versions here.

Yeah, I know this is a blog about Linux in the US, and specifically in the East — but if you check us out regularly or have us in your RSS reader, you should know that we also occasionally visit other parts of the world to see how they’re doing.

Here’s a little article from ZDnet Asia/Bangkok Post whose reporter sat down with Novell’s Executive VP of Worldwide Sales, Tom Francese, to see how things were coming along…

“We’re an information infrastructure company. We are different from RedHat in that we deliver up the stack–security, systems management, virtualization–and we are more than just open source,” Francese explained.

…and…

In Thailand, some of Novell’s reference customers are Thai Airways and Assumption University. The Ministry of Interior is also of note, as it progressed from being a heritage customer using Netware through to security and today’s OS stack.

The government sector is one where Novell is particularly strong. The Indian state of Tamil Nadu recently rolled out 2,000 servers and 40,000 desktops all based on Suse. Novell is also looking to the government sectors in China and Japan, as well as here in Thailand.

Will Virtualization Doom Server Sales?

From the article:

The promise behind virtualization has long been that one well-equipped server could do the work of several. So what happens once customers begin following that idea — and buying fewer servers?

That scenario is cause for concern, according to industry analyst Infiniti Research. This week, the firm published a study indicating that server sales will trail off in coming years, and even decline, as virtualization reduces the need for physical hardware.

The company’s TechNavio online research unit released the findings to coincide with the upcoming Storage Expo conference in London next week.

The study suggests that sales will slow to two percent in 2008 — representing a marked decline from the 5.9 percent annual growth rates that fellow market researcher IDC saw in 2006, and the 8.9 percent from a recent Gartner study.

Read the rest of the article.

According to a Silicon.com article… Speaking to an audience at the Gartner Symposium/IT Expo last week, Dell’s CEO Michael Dell said that Linux server sales are increasing faster than Windows server sales. You can view the webcast of the keynote here. I think that helps to validate what many of us have intuitively known for years… that Linux is the fastest growing operating system in the IT market. It’s also worth pointing out that Dell is validating the observation we’ve had for some time that more and more organizations are “trusting” Linux A LOT more and deciding to put more “critical applications” on Linux than in the past.

He said: “On the server side Linux continues to grow nicely, a bit faster than Windows. We’re seeing a move to Linux in critical applications, and Linux migration has not slowed down.”

However, for those customers who might be concerned about whether Microsoft’s claims of patent violation could result in legal action, Dell added that there were “certainly mechanisms if customers are concerned about patents”.

One of those mechanisms he’s referring to is Novell’s own Novell Technology Assurance Program (NTAP). Whether or not you believe MS’s position on IP, there are surely CxO’s within your organization who prefer to minimize all risks for the organization. NTAP can certainly help give those CxO’s the piece-of-mind necessary, and help remove roadblocks for you to dramatically increase the amount of Linux in your shop — (assuming you like secure, reliable, and low cost operating systems… like SLE) 🙂

Many small businesses and the IT consultants who support them have deployed Linux in some way — hey, it can save a ton of cash! But typically Linux is doing a specific task — maybe a file/print server, web server, firewall, database, etc. The solutions have been done fairly piece-wise, and that can lead to a lack of integration – making things a bit more difficult to manage over time. Alternatively, one might have chosen the Microsoft Small Business product – but we all know where that can lead (security problems, constant patching, IT headaches, excessive software costs, etc.). There really hasn’t been a nicely integrated workgroup suite for small business based combining the best of open source and proprietary enterprise software… until now.

Novell Open Workgroup Suite Small Business Edition has arrived. It works with either Windows or Linux desktops and includes “less expensive” (and arguably EASIER-to-LEARN) alternatives to Windows Vista and MS Office 2007. In addition to a nicely integrated installation, it has a ton of value for a very small price. It includes:

  • File/Print sharing and security – Open Enterprise Server for Linux
  • Laptop backup/file collaboration – iFolder
  • Email/Calendaring – GroupWise
  • End-user general purpose desktop – SUSE Linux Enterprise Desktop
  • MS Office-compatible office suite – OpenOffice.org, Novell Edition
  • Backup software – Amanda
  • Network faxing – HylaFAX
  • Anti-spam – MailScanner
  • Anti-virus for email – ClamAV
  • Firewall – iptables
  • VPN – OpenVPN
  • Remote control – TightVNC

… and all this stuff runs on Linux!  Yeah, but how does it compare to the Microsoft Small Business Suite? Look here.

All this for a retail cost of $350 for every 5-users!! Want more info? Check these out… product home page, audio podcast, press release, workgroup team blog

A new Aberdeen Group study reports that as Virtualization keeps expanding both in it’s role in the datacenter and as a tool for consolidation of services/storage and cost savings, it’s becoming even more vital as a way to provide Business Continuity, High Availability and Disaster Recovery.

For us, virtualization is a given. Our system utilization was low and if there was a peak, it only happened for an hour.

The rest of the time our systems are idle. Our application servers are just not using enough of the physical resources.

— Manager of Portal Operations for a Consumer and Applications Portal Company

The report includes a number of case studies and significant findings, such as:

  • 54% of firms use virtualization to support DR plans
  • 48% use virtualization to support HA strategies
  • 50% use virtualization to support BC implementation

For the typical organization who suffers from excess capacity and the costs associated, virtualization is a must. Along with that move to enterprise level virtualization comes the need for enterprise level business continuity planning.

Since the use of virtualization for BC, HA, and DR purposes is still merging, it is imperative that companies make sure it is implemented with the careful planning and testing of systems. This also will help insure there are no unnecessary redundancies and more efficient process in data recovery management. This latter issue, which is just starting to take hold within the physical world, is certainly going to be the next big issue as more companies use virtualization to support BC, HA, and DR processes.

Recovering data generated from virtualized systems will become a crucial discussion in the coming months.

Never one to do anything in a small way, CSFB has plans to continue their use of virtualization using rations of up to 15:1.

“With 20,000 servers to manage, financial services powerhouse Credit Suisse had a long list of reasons to consider server virtualization: reducing the number of physical servers to manage, cutting power needs, improving software provisioning time, and deferring expensive datacenter buildouts. But it also needed a clear set of guidelines to determine when to virtualize, plus a clear set of procedures for managing a virtualization initiative.”

More on Credit Suisse’s progress.

As if there weren’t currently enough companies with a virtualization play, Hitachi has announced that it has placed it’s Virtage virtualization code on the firmware for it’s Xeon-based blade solution, the BladeSymphony 1000, which combines Itanium and Xeon CPU’s in a single chassis.

More here.

Nationwide Insurance is a posterchild for the right use of virtualization, on all their platforms. A huge IBM Mainframe shop, they also use Linux in their X86 environment to cut costs and be more green.

“While many IT shops see virtualization as a question of adopting EMC’s VMware on servers running Windows or Linux, Nationwide Insurance has adopted the technology for both x86-based and mainframe-hosted servers.  After all,” notes Buzz Woeckener, the company’s zLinux/Unix server manager, “virtualization was invented for mainframes.”

More on Nationwide’s virtual environment

I’d buy that for a dollar. Well, lots of dollars, since it’s priced similarly to our friends at IBM’s mainframes. PSI (Platform Technologies Inc.) makes a plug-compatible set of machines called the System64 DS and ES, formerly only available through a 3rd party.

DS or Distributed Server and the ES or Enterprise Server hardware are currently shipping to early adopters and are competitively priced with IBM’s per-MIPS pricing of approximately $1200 to $1400.

The key to PSI’s systems are the ability to not only run OS/390 (IBM’s Mainframe OS) but also Linux and Windows. The DS system sports up to 8 Itanium v2 CPU’s and the ES supports up to 64 Itanium cores. Both support the production versions of z/OS, OS/390, HP-UX, Linux including SLES and Windows Server versions.

“Our customers have repeatedly told us that standardization and virtualization are key to their business success and an imperative for their IT strategy – today and for the future. We’ve developed the System64 product line to meet the industry’s challenges and drive customers’ success.”

You can get a lot more information from the PSI site, including quotes and whitepapers.
